Fathers and testosterone.

Well, the BBC web site actually published something moderately favorable to fathers. It seems that fathers have significantly lower testosterone levels - "the lower levels of testosterone in fathers may reflect both their withdrawal from the competitive arena and their involvement in paternal care."

But "A UK expert said the fall was nature's way of ensuring men behaved in a "civilised" and non-aggressive way around newborn offspring.", so if you're not a father, you're still an animal who can't be trusted to behave himself. Sigh.

Nevertheless, perhaps this might add some weight to the idea that being a father has some significance and consequences for a man although it appalls me that this has to be pointed out at all.
